Updated foliage and shadows in the World Engine runtime

I installed the newer shipped World Engine source and merged the existing Feathers climbing and collision additions.

The update includes foliage detail levels, shadows and distant-tree shading. Character assets and authored world settings were preserved.

The footage uses the current Wilds level and native powered wingbeats to show the environment during flight. Any initial airborne setup is recorded in capture provenance.

Optional temporal support remains off by default. The source and both-backend checks passed, but this entry does not claim a measured performance gain or a completed outdoor polish pass.
